And we've posted about Tennessee's Evelyn "Mama Bird" Johnson, who died last week at the age of 102. She held the Guinness world record for most hours logged by a female pilot.

Now we're hearing about Marie Kelleher in Virginia, who at the age of 99 is still setting swimming age-group records. Counted as being 100 because United States Masters Swimming rules "use the swimmer's age as of December 31 for competitions held in 25-meter courses," according to Virginia Masters Swimming, she just became "the oldest known American woman to have competed at a USMS-recognized meet."

The Richmond Times-Dispatch says that "Kelleher swims four days a week, usually logging about 10 laps per session. She arrives at the Tuckahoe YMCA at 5 a.m. on her swimming days, driving herself 9 miles from her home to arrive exactly when the Y opens."

"I need the swimming," she told the newspaper, with a grin. "I'm not much at walking anymore. ... I told somebody recently that I staggered when I walk. He said that didn't sound too good. So let's just say I wobble."
